relationship between hardness and Young's modulus in polymers

relationship between hardness and Young's modulus in polymers

(OP)
Is there a reliable equation relating hardness to Young's modulus for polymers? I have a piece of polymer that would be hard for me to machine into a good tensile testing sample but it might be easy to perform a hardness test.

Please help.  

RE: relationship between hardness and Young's modulus in polymers

I guess if that worked then everyone would be doing it. Sounds interesting, though.

RE: relationship between hardness and Young's modulus in polymers

No.  
Hardness is mostly driven by strength, though in low modulus materials there is a stiffness component.
If you are working with a type of hardness measurement that is in the fully elastic range then you might be able to develop one.

agb...I can't imagine such a correlation being very accurate if one exists at all.

Have you considered freezing the polymer before/during machining?
